Probability and Statistics-Simple linear regression is performed to analyze the relationship between the X and Y variable. The least-squares regression line is found to be Y =1+.34X. Interpret the relationship between X and Y. O Since the slope is .34, X increases at a slower rate than Y. O Since the slope is.34, Y increases at a slower rate than X. O Since the slope is 1, X and Y both increase at the same rate. O Since the slope is 1, there is no relationship between X and Y
